Ron is a big part of this. He is a libertarian, an old-school traditional man, a source of humorous conflict for the progressive Leslie. But as time goes on, it becomes increasingly obvious that this character cannot exist in the new order. So he is increasingly neutered- not with his ex-wives, which I think is just a humorous subplot. But he basically comes to agree with Leslie on literally everything, spouting off a libertarian one-liner while totally embodying her entire worldview. He is subsumed into this triumphalism. Obamaism and this show posited that the Republican had been defeated, and now only had to be slowly digested into the new Utopia. Parks & Rec is the perfect piece of media for explaining the world-shattering shock that liberalism felt on Nov 8, 2016.
